ThermoWorks RTR-500GSM WIRELESS LAN OR GSM (CELLULAR) LOGGERS - Manual (Page 2)

Getting Started
I) Connect the RTR-500GSM to your PC
First make sure the Run / Stby switch is in the Stby position
and plug in the A/C adapter. Next plug the RTR-500GSM
into a USB port on your PC. The RTR-500GSM Settings
Utility should open automatically as shown here. If not, go
to your Start Menu and open the software.
II) Check the Following Points
A) Check the LED’s on the front of the RTR-500GSM unit. If the orange ERR LED is on steady there is a problem with the SIM
card. It is either installed incorrectly, invalid, locked or defective. You can go no further until this condition is corrected.
B) In the normal case you should see the green PWR LED turn on steady for a bit, blink for a few moments while the unit
communicates with the PC through the USB connection, and then remain on steady. The unit can take its power from the USB
port but not all functions will be enabled. Make sure you install the batteries or plug in an A/C adapter to continue, even
thought the unit seems to be working fine at this point.
C) After downloading for a few moments you should see the RTR-500GSM appear in the Settings Utility window, as shown
above. If this does not happen, the most likely cause is a problem with the USB driver which needs to be corrected before
proceeding. Again, there are very complete instructions for installing the USB driver in the Introductory Manual starting on
Page 25.
D) At this point, the first time a new RTR-500GSM is connected the Initial Settings Wizard should open. If it doesn’t you can
open it manually by clicking on View > Initial Settings Wizard from the pull down menu. For subsequent connections the main
settings window would open.
